Fan Maintenance


Frequent inspection should be made of the fan.

General inspection of the fan will depend on how essential the service, the application operating environment and number of hours run, but should not be more than three monthly intervals.

On fans operating in dusty atmospheres or exposed to weather then the bearing will need to be flushed out and replenished with grease every six months.

Recommended Lubricants
